STAPLE BINDER.

Application 1ed October 20, 1921. Serial No. 509,067'.

To aZZ whom t may concern.'

Be it known that I, DANIEL L. InvrN, a citizen of the United States,residing at Curwensville, in thecounty ot Clearfield and State otPennsylvania, have invented certain new and useful Improvements inStaple Binders, ot which the 'tollowing is a specification.

My invention relates to improvements in staple binders, of' the formshown in the application tiled May 9, 1921, Serial No. 167, 936, byBerthold Jahn andY Ernest Emil Kahl, and the patents issued'under dateof August 9, 1.921, to said Jahn and KahhNos.

" 1,387,268 and 1,387,269, and the object of my improvement is toincorporate in a structure ot the general form mentioned means torcooperating with the individual staple that is in the path of theplunger and is the next to be severed from the staple strip and drivenby the operation of the plunger, whereby said individual staple will bepositioned and directed tor properly cooperating .with the plunger andthe anvil in effecting the binding ot materials thatare operated upon inthe'useof the binder in the usual-and or- -dinary manner. v

In the accompanying drawngz- Figure 1 is a side elevation ot my improvedstaple binder.

Figure 9 is a side elevation inpart broken away. y *l The staplevbiiider to whichmy invention `is applied'niay correspond in the generaltorni' to any oltthose shown and described in any of the patents or theapplication menioned or to other devices that operate on a staple stripof similar torni to the strip shownrin Fig. S, so that a briefdescriptifs; of suc-h general structure will sutlice in the presentinstance. Y

Such aggeneral structure comprises a base 10 having at the front end theanvil 11 tot elenching the staples 1 2 in cooperation with n VJtheplunger 13 atter they have been severed and a moving member, designatedgenerally by the cliaracter'lG, is operatively connected thereto by thepivotal pin 15.

A vpair ot' ways 1T at the tront'part' ot the;`

moving meinber16,position-ed in spaced relation, engage v` with the sideedge portions ot theplunger 13 andserve to guide the plunger'in itsupwardk and downward movement. llhe tiller piece 18 that extends alongthe bottom ot the moving Ymember 16, and is op-y posed to the base 10,is positioned between the two side plates 19 ot the frame'or casing; hasthe upper portion 2O reduced in width so as to serve as the guide ttorthe staple strip; supports by its front end the die. 21; supports by thelower portion 22 suitable dowel pins for positioning the side plates 19;andhas the rear end" portion extended between the ears 14C and pivotallysupported by the pin 15.

The said bottom portion alsoY has holes for the two holding screws forholding the side plates 19 in place, comprising the screw 2t at the rearand the screw 25 at the front. The front screw serv-es also as the meansfor holding the` die 21 in place, said die 21 being in the form et aremovable piece.

Theupper part ot' the casingtor the moving member 16 is formed by theside plates 19 which have their body portions positioned in spacedrelation to provide a housing for the staple moving'or tee-dingmechanism that cooperates with the plunger 18. The form ot the saidupper part ot the casing is general` ly triangular, with a sloping orinclined rear and' upper wall 26, and the closure for the Said rear andupper' portion provided by means of iinvardl),Y turnedI` opposed flangesil? on the eide platee lil.
